COMBINATION HEATING APPARATUS.

Application filed January 7, 1926.

My invention relates to improvements in heating apparatus, and theobject .of my improvement is to eiiect a combination system for heatingby means of hot water directly and steam indirectly, the steam beingutilized for heating the water, and provision being made 'for regulationof the steamdelivery, the regulating means being directly actuated bythe heated water.

This object I have accomplished by the means which are hereinafterdescribed and claimed, and which are illustrated in the accompanyingdrawings, it being` understood that changes in the precise embodimentoi? invention herein disclosed can be made within the scope of what isclaimed without dcpartingfrom the spirit of the invention.

In said drawings, Fig. 1 is a vertical longitudinal medial section of aheating radiator of the built up sectional type for heating directly bymeans of hot water, the view being diagrammatic, with parts broken away,and Fig. 2 is a like section, but showing a modification in the steamregulating means, which are illustrated in detail, 'fragmentarily, withother parts removed.

The radiator is built up of connected hollow sections 1 of a well-knowntype, having sleeve connections 2 above and below to permit circulationof water therethrough. One of these sections may be supplied with waterat the top by a pipe 3 which may communicate with any source of watersupply or with an expansion tank 4 located above the radiator.

The numeral 5 denotes a steam outlet pipe which centrally traverses therow of lower sleeves 2 and clamping screw plugs fitted in threaded seatsin the end sections 1. This pipe 5 is in a steam circuit of piping toand from a source of steam under pressure, and at one end o the radiatorincludes a valve-chamber 6 in the communications, between said pipe 5and an inlet pipe 7.

This valve-chamber and its regulating valve may be of any desired kind,other than that shown. The one illustrated comprises within said chamber6 a closed hollow body 8 threaded upon the end of the pipe 5 and havinga flat top provided with a beveled valve-seat 9 to receive and fit abeveled valvehead 10 adjustably mounted upon threads on the lower end ofa vertical valve-rod 12 which traverses slidably a stuffing-box 11.

The numeral 21 denotes an elongated rod Serial No. 79,778.

preferably ot aluminum or other metal which possesses a high degree ofcoeiiciency of expansion, and which has a rigid bracket connection atone, its inner end, to and within one of the upper sleeves 2, it beingunderstood that this sleeve is rigidly mounted in its seat, so that itbecomes an abutment for this end oi the rod.

The other end oi' the rod 21 is passed through a stui'ling-box 2Ooutwardly and projecting into a casing 13 which is bracketed to theupper end ot the outer section 1. This casing has a downturned open end111 into which extends the upper end of the valverod 12. A bell-cranklever 15 has one end pivoted at 19 to the outer end of the rod 21, isfulcrumed near said pivot on a cross-pintle 18, and has its longermember provided with a short slot 17 to receive a pin 16 projecting fromthe valve-rod 12.

rllhe valve-head 1() is to be adjusted upon the rod 12 so that it isspaced a proper distance above the valve-seat 9 when the water in theradiator sections 1 is cool. Steam then passing said valve-seat throughthe pipe 5 heats the water in the radiator in which it is immersedthrough conduction through the pipe but there is no communicationbetween the pipe 5 and the interior water-containing space of theradiator. As the water becomes thus heated, the rod 21 graduallylengthens until a desired maximum temperature thereof is arrived at, bywhich time the valvehead 10 has nearly if not quite closed thevalve-seat 9. The gradual contraction oit' the steam passage by way ofsaid valve in shutting ott the steam proportionally, correspondinglylowers the temperature of the water, or rather, tends to bring thetemperature of the water in the radiator to the critical degree, wherebyan even temperature is automatically maintained.

In this device the regulator shown in Fig. 1 is actuated by the heatextension of the rod 21, but in the modification illustrated in Fig. 2,a regulating device of a similar mechanically moving type is used, theexpansion of heated water in the radiator serving as the motive agent.In this installation, no eX- pansion tank 4 is used, as the water shouldbe confined within the radiator closely, although any kind ot well-knownresilientlycontrolled safety-release may be inserted in the radiator toeject water when compression has passed above a critical amount.

As Lthe water, however, is lusually not `to be heated foyer a.unoilerate temperature, an open-end cylinder of a proper capacity Visplaced in communication With the upper part of 'the radiator anddetachably secured thereto and contains a flexibly packed imperforatepiston 25, the latter ,having ,a -stein 23 slidably traversing theapertured closed end of the cylinder andalso a Ystuiiing-bou 2O to entera bracketed hollow casing 24 which iclosed :at its outer :end iby '.aremovable plug. iFhe .casing 12a `ihas lvertically alined apertures.near its outer end through which is ipassed Athe .upper :part of. theualwerod 112 to project thereabove with .a .threaded .end

Y 28 ica-rrying a 4compresSion-:nut 27. Acoiled compression-spring .26is .engaged between the top of' said casing land said nut 27'., :and thelatter may .place the spring Vunder .an adjustable =.coinpreesion.

vits .the .radiator Water .is :heated Iit expands, and pushes thepistonl2`5 into `said cylinder, to :cause .its fstem to ,rock `thebell-orank `lever 1:5 .to lower .the rv'alv-e-.rod l2, .thus 'causingthe ualveehead ito .control vthe steam .passn ing through thevalve-.seat 9, in like =inanner to the irstamention@d :regulatingdevice.

It Will be .understood that in this manner all :the radiator-fsassembled in a building' may be `automatically controlled, Aandindependently regulated, and thatthe itwo means described :foriactuating the regulating .de-

vice, .as Welles othersef Lthe,eenera,.are in* dluded 4iin linyinvention, ithe gist oi which is the regulation of the steam pressure bythe Water condition automatically.

This 'invention thus confers upon the user the -benefit of Water heatingof an evenly maintained desi-red maximum temperature, While using aneasily generated steam supply dior itfhe heating agent, more responsiveand economical than more complicated kinds ont heating apparatus.

Having described my invention, what l claim :as .nenv, :and 'desire tosecure by 'Letters Patent, is:
